Release Notes: gsm-ussd now correctly creates lock files for the serial interface in use or quits if there is already one. If the modem is newly registered in its net, it is now given a little more time to settle before USSD queries are sent.

Release Notes: Better handling of USSD response encodings, thus support for ZTE MF100 has been added. Handling of the serial interface is now done without stty, saving an external dependency and three processes per gsm-ussd call. User visible changes: xussd will now ask for queries until canceled, thus allowing the user to react to USSD sessions.

Release Notes: USSD sessions are now supported. If you get a USSD response of type 1 (Further action required), gsm-ussd tells you that you have an open session. You can then use gsm-ussd to push your data into that session, or call it with "--cancel" to abort the session.

Release Notes: A bug has been fixed: xussd wasn't switched back to the installed version of gsm-ussd, but still tried to use the local repo gsm-ussd. If you installed v0.2.3, xussd will not be able to find gsm-ussd.

Release Notes: Certain modem/SIM combinations have echo enabled at the interface as well as the modem level, breaking previous versions of gsm-ussd. This version will set a defined state for the interface and the modem and restore the interface settings after use. Also, xussd will now only ask for the SIM PIN if needed.

Release Notes: Some more modems were tested. A list of Huawei modems which need PDU mode for USSD queries are checked, so that the right mode can be chosen automatically. Before sending a query, the program checks whether the modem is registered to a network up to ten times, or until the modem indicates that it is not willing or allowed to register. If network/equipment errors are reported as numbers, these are translated into English error messages. USSD response types are shown in debug output and values of 1 are reported as "Further action required".
